摘要： A taper point surgical needle having improved needle point strength is disclosed. In one embodiment of the needle, a tip portion includes first and second integral tapered regions having first and second cross-sectional areas respectively which decrease progressively toward the tip of the needle in accordance with first and second angles of inclination respectively, with the first angle being greater than the second angle. In another embodiment of the needle of the present invention, the tip portion includes a third tapered region integral with the second tapered region and having a cross-sectional area which decreases progressively toward the needle tip in accordance with a third angle of inclination which is smaller than the second angle.

摘要： A polymer, particularly a biomedical polymer for the fabrication of medical and surgical devices and for use as a coating, is described. The polymer is derived from the reaction product of one or more lactone monomers and castor oil preferably: (a) .epsilon.-caprolactone, trimethylene carbonate or an ether lactone; (b) castor oil; and (c) glycolide, lactide or 1,4-dioxanone. The preferred polymer is derived from .epsilon.-caprolactone, castor oil, and glycolide.The polymer in preferred embodiments is ideally suited for use as a coating for a surgical suture, particularly an absorbable, braided multifilament suture and surgical needles. For this application, glycerol is advantageously added to the reactive monomer mix from which the polymer is derived.

摘要： A temporary cardiac pacing wire, or a similar device, includes a pair of flexible electrode wires extending conjointly from a distal end of the pacing wire to its proximal end, where two electrically conductive sections are located. The conductive sections are suitable for connection to a power source adapted to generate electrical signals for stimulating, pacing, sensing, monitoring or defibrillating the heart of a patient. One conductive section results from the distal end of a Keith-type needle that breaks away from the rest of the needle. The other conductive section is arranged at the free end of a third electrode wire which is movable independently of the other two electrode wires, thereby permitting its connection to the power source in a plug-like fashion.

摘要： A temporary cardiac pacing wire (TPW) includes an electrically conductive flexible wire having a bioabsorbable anchor near its distal end. The anchor includes a tubular section that surrounds the wire and a leg that extends from the tubular section at an acute angle to the wire. The bioabsorbable anchor causes minimal trauma to the heart when it is inserted with the TPW, but securely anchors the TPW in the heart. After the TPW is no longer needed, it can be removed, again with minimal trauma to the heart, leaving behind only the bioabsorbable anchor. The bioabsorbable anchor is suitable for use with both monopolar and bipolar TPWs.

摘要： A process for the manufacture of suture needles and, more particularly, a process for enhancing the physical strength of the suture needles through an expedient cold-working or cold-forming procedure. Also disclosed is the provision of a novel and physically strengthened suture needle, particularly a surgical suture needle possessing a curvilinear configuration wherein the cross-sectional configuration of the needle is cold-formed into varying shapes in order to produce a needle having superior physical characteristics and strengths imparted thereto through the inventive process. The needles are essentially cold formed, and which process includes the aspect of imparting to straight metal rods which are preferably constituted from stainless steel, manufacturing steps which include sharpening one end of rod severed segments so as to form the needle tip, thereafter curving the needle with the metal still being in a relatively ductile state, and subjecting the needle to a cold forming process, such as through the intermediary of pressure die molds or stamping, to produce varying cross-sectional shapes along the length of the needle.

摘要： The present invention is directed to a wound drain catheter for draining fluid from, or supplying medication to, a wound in a patient. The wound drain catheter comprises a drain, a flexible outflow tube, and means for connecting the drain to the flexible outflow tube. The drain comprises a hollow core having a longitudinal axis; plural struts extending outwardly from the hollow core and being closed to the hollow core; and plural overhangs connected to the outward ends of the struts, respectively, the overhangs cooperating with the struts to form plural longitudinal lumens, the overhangs cooperating with each other to form, on the outer surface of the drain, segments of a segmented, closed curve with gaps between the segments providing plural longitudinal grooves for fluid communication between the wound and a respective lumen, the grooves sized to inhibit tissue from growing therein and debris from passing therethrough. The present invention also includes a method for draining fluid from, or supplying medication to, a wound in a patient.

摘要： A temporary cardiac pacing wire, or a similar device, includes an electrically conductive lead which is folded over on itself so as to be adapted for connection to a pacing or monitoring apparatus. In the case of a bipolar temporary cardiac pacing wire, flexible wires are employed having two elongated conductive sections at a proximal end. The conductive sections are suitable for connecting to a power source adapted to generate electrical signals for stimulating, pacing, sensing, monitoring or defibrillating the heart of a patient. One conductive section results from the distal end of a Keith-type needle that breaks away from the rest of the needle. This section is suitable for directly connecting to the power source. The other conductive section is suitable for connecting to the power source when folded over on itself.

摘要： A device for sealing puncture wounds in blood vessels is open at one end and closed at the other end. The tube closure is generally flat and pivotable, and the tube region near the closed end is expandable. The device is initially contained in a sleeve, which is inserted through a cannula, so that the closed end is within the vessel to be sealed. After the cannula is removed, the closure is pivoted and the device withdrawn to a point where the closure abuts the puncture wound. After the sleeve is removed, the expandable region is expanded, so that the blood vessel wall around the puncture is sandwiched between the closure and the expanded region. The device prevents blood from seeping out of the punctured vessel during the healing process.
